常量字段值

MEMBER_MAJORITY_ADD_KEY

static final String MEMBER_MAJORITY_ADD_KEY

Does it allow majority-add, i.e. adding a majority of members in a single setConf?

Note that, when a single setConf removes and adds members at the same time, the majority is counted after the removal. For examples, setConf to a 3-member group by adding 2 new members is NOT a majority-add. However, setConf to a 3-member group by removing 2 of members and adding 2 new members is a majority-add.

Note also that adding 1 new member to an 1-member group is always allowed, although it is a majority-add.

MEMBER_MAJORITY_ADD_DEFAULT

static final boolean MEMBER_MAJORITY_ADD_DEFAULT
